Improvement in fliers for spinning



UNITED STATES PATENT OEEICE.

IMPROVEMENT IN FLIERS FOR SPINNING.

Specication forming part of Letters Patent No. 53,874, dated April 10, 1866.

To all whom it may concern:

Be it known that I, GEORGE RICHARDSON, of Lowell, in the county ot` Middlesex and State of Massachusetts, have invented new and useful Improvements in Fliers; and I do hereby declare that the following is a full and exact description thereof', reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in the arrangement and construction ofthe arms of a hier in connection with the headless bobbin.

To enable others skilled in Athe art to make and use my invention, I will proceed to describe its construction and operation.

Figure l represents a plan ot' my improved flier. Fig. 2 represents a front elevation of the same with the headless bobbin. Fig. 8 represents a side elevation ot' my improved ilier.

a represents the tlier-bottom; b, the arms; c, the nose; d, the headless bobbin, and e the threadguides.

Hitherto the manufacturer has been unable to run a Hier at a speed exceeding four thousand tive hundred turns per minute, for if the above speed is exceeded the arms are thrown out of their natural, true, and proper position by the centrifugal force, Awhich shortens the hier and renders the arms very liable to break at the point where the thread-guides are inserted, besides throwing it out of balance. Besides, ordinarily in I'liers, the arms being of the same size from the nose to the bottom and straight, at the above speed the resistance ot' the arms to the air causes extra power to run them. Also, in the use of its attendant bobbin with heads, which are used in the ordinary or common way ot' spinning yarn in the rst stages of spinning, when the yarn begins to wind on the barrel of the bobbin, the yarn being so near its axis, it requires nearly all, and oftentimes more than, the entire strength of the yarn to drive or revolve the bobbin, owing to the superfluous weight of its heads. Then this occurs the yarn invariably breaks, causing loss of time and stock to the manu facturer.

In my improved flier, in connection With the headless bobbin a, all these defects are remedied. In the construction and curved form of the arms b of the iiier of my invention the advantages are such that the greatest strength is retained in the center of the arms b, as seen at section B, as at this point the greatest danger exists in breaking and springing outward, and from this point to the bottom a and nose c, as seen at section A and C, the arms b are reduced one-half size, lessening its weight. Further, the arms b, being flat on the inside and semicircular on the outside, as seen at section A and C, and three-quarters ot' a circle, as seen at section B, when the tlier is at high speed the resistance to the air actually counteracts the centrifugal force at the center ot' the arms b, which causes or keeps the arms b in their original and natural curved shape. This form and shape ot' the arms of the iier produces much less resistance to the air when at speed the same as that ot the common ilier. Besides, the headless bobbin d running in conv nection with a Hier, the weight being much less than the common bobbin With heads,the yarn is kept at aproper tension when the Hier is at high speed, which prevents, by its lightness, the yarn from breaking, and when the Hier is stopped to dott', or for any other purpose, the same cause has a tendency to stop the bobbin d instantly, thereby preventing kinks4 or entanglements, and thereby avoids great waste of the yarn and et't'ects great saving to the manufacturer.

IVhat I claim as my invention, and desire to secure by Letters Patent, is-

l. The elliptical form and semicircular shape of the arms I), as herein specied, and for the purpose set forth.

2. The headless bobbin d, in combination with a flier constructed as herein described.
